I recently asked my doc (maxillofacial surgeon) about the differences and similarities of the two. Genioplasty seems to be very similar to a genioglossus advancement (GA) in that they both help pull the genioglossus muscle/tongue forward. My understanding is that with genioplasty the tip of the chin bone is sliced and pulled forward. www.srt-psc.com/8case99.html (My understanding is that the genioglossus muscle/tongue is attached to this tip and therefore helps pull the tongue forward. With the GA, the same results are accomplished via a small window of bone which is pulled forward. Genioplasty might be more preferrable if you also desire cosmetic enhancements for a small chin. But if you have a normal-sized chin, a GA might be more preferable since it wouldn't alter the profile as much.).
As for its effectiveness, I'm guessing a genioplasty might be as effective as a GA. I'm only guessing though... I haven't really come across any clinical studies on genioplasty per se, just with GA. As for the GA, I hear success/cure rates quoted around 40% ~ 75% depending on the severity of the apnea. If you suffer from severe apnea then there's less chance of being completely cured, but it may help lower the RDI and lessen the severity of the apnea.
